IMPROVEMENT IN WAGON-BEDS.A

The Schedule referred to ln these Lettera Patent and making part of the same.

* Hro--a To all whom tt may concern:

Be it known that I, WILLIAM H. PORTER, of Brazil, in the county of Clay and State of Indiana, have invented a new and useful l mprovement in W'agon-Beds; and I do hereby declare that the fullo-wing is a full, elear,'and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying`dr"a\ving forming partot' this specification.

This invention relates to improvements -in wagonbeds, platforms, or boxes, and consists in certain improvements' in the construction and arrangements thereof, and of the connections of the brake-actuating levers, calculated to provide the most substantial and durable boxes or beds, and' brake apparatus that may be, all as hereinafter described.

Figure l is a side elevation of my improvedv wagonbed o'r box, a part, at one end, being sectioned.

Figure 2 is a plan of the bottom of the same; and

Figure 3 is an end view. A Similar letters of reference indicate corresponding parts.

I propose to. employ the grooved meta-l plates A with notched or recessed horizontal parts B, for the support ot' the head and tail-boards O D, and the transverse bars E, on which the ends of the bottom boards F rest, the said plates A B being attached to .the side boards U, Aas shown.

llhese plates are preferably made by casting, and may be malleableized, if preferred. The bars E are preferably made of wrought metal, but bars of strong wood will answer the purpose well.

The edges of the bottom boards are suitably notched, to .permit the bars A B toeXtend below them, and the shoulders of these notches, acting onv the said bars, prevent the boards from working endwise.

H is the cross-bar, for supporting the bottom boards at the center. It is suspended bythe straps I from the side boards, and slides between the blocks K, attachcd to the center boards of the bottom, which are beveled, and arranged to form a dovetail groove for the said cross-bar pH; .these prevent the center board from sliding endwise.

The brakes are attached to the leversLM, andthese are connected by the clevis N, in which the end vof the lever L is arranged to play freely toward and from the lever lVLaud a spring, O, is applied to the lever L, and arranged in the elevis N, so as to press the end of said lever toward the lever M.

The object of this arrangement is to compensate forany.irregularities which may existin the rims of the wheels, or in the'atljustment of the brakes relatively to each other and the wheels, for, if the brakes are so conneetedas to move exact-ly alike, one might bear on the wheel to which it is connected, and the other not. v

The lever M is extended from where the two are connected together to the side of the box, as shown,

. and is there connected by the rod P'to the ,brakelever Q. A

' Having thus described my invention,

I claim as new and desire to secure by Letters Patent- 1. rlhe combination, with the side boards, end

boards, and the bottom boards, of the plates A B 'and the bars E, substantially as specified.

2. The combination, with the brake-levers L M, ot

lthe elevis N, and spring O, substantially as specified.
